Abstract Two metal–organic frameworks, [Cu(cptpy)(NO3)]·DMF·2H2O (1) and [Zn3(cptpy)3(NO3)2(H2O)4]·NO3·5DMF·2H2O (2), were solvothermally obtained with carboxyphenyl–terpyridine ligand (4-(4-carboxyphenyl)-2,2′:4′,4″-terpyridine) (Hcptpy). Complex 1 reveals a 3D 4-fold interpenetrating network with ths topology, and complex 2 exhibits a 2D layer structure with hcb topology. Notably, the luminescent properties of complex 2 dispersed in different solvents have been investigated systematically, demonstrating high sensitivity for the detection of nitrobenzene via a fluorescence quenching mechanism. Furthermore, related to its cationic framework, 2 displays efficient removal of anion pollutants Cr2O72− from aqueous solutions.
